[QUOTE=exbayern;20344340]The machines at the station sell both types of tickets.

I don't know what this means? Is this supposed to be something we have here, or perhaps a translation of something?

Anyone travelling to/from CDG via the RER this winter should be aware that due to ongoing works on the weekends service is interrupted and there is often a bus connection as a result. This continues into March.

I apologize for the strange wording. I was using siri on my iphone, and it misunderstood, and I missed that. Thanks for the heads up for the track work. Is there a website that I can check for updates?
